How did Sai Baba produce the Udi, and what was its role in granting devotees permission to leave Shirdi, as detailed in Chapter 33?

Chapter 33 explains that Sai Baba produced the Udi from the sacred fire, or Dhuni, which he kept perpetually burning in the Masjid. He would purchase and pile up bundles of firewood logs and offer them to the fire. The ash that remained from these burnt logs was the sacred Udi. This chapter highlights a specific and important practice: when devotees sought Baba's permission to return to their villages, he would give them Udi. This act of receiving the Udi was understood by all as the true signal that permission to depart was granted, filling the devotees with enthusiasm for their journey, as they carried his tangible blessing with them.
